Nano-fibers can delay the virus

The nano-fibers we previously made for membranes can also be used in breathe filters to protect against viruses.

Nano-fibers on tweezers


Nano-fibers (white) between layers of nonwoven fabric, filter preparation

We fabricated test filters and tested kerosene soot with nano-particles, the average size of which is less than 130 nm.
